A Pokemon GO player ran into a shiny Yungoos, but they didn't have any Poke Balls to actually catch the creature. Pokemon GO has all kinds of super-rare Pokemon for players to catch and add to their collections, with shiny variants being among the rarest in the game. The "shiny" concept has been a part of the Pokemon experience for decades now, with fans still dedicating great amounts of time to catching as many shiny Pokemon as possible.
